Coauthors Preethi Bhaskar, Milind Mujumdar, R. H. Kripalani, A. Prabhu, and R. Krishnan, explored the recent trends, variations and teleconnections between two Asian monsoon sub-systems viz., the South Asian and the East Asian monsoons. The findings based on century long precipitation records depict a dipole-type configuration with a north-deficit and south-excess pattern over both the sub-systems. The trends in the spatial distribution of mean sea level pressure and lower tropospheric winds during the post-1970s indicate a westward shift of summertime large-scale circulation features, such as the South Asian summer monsoon trough and the North Pacific Subtropical High, which are dynamically consistent with the recent trends in summer monsoon precipitation over the Asian monsoon sub-systems.
